Abstract
The preparation and characterization of Adsorbent from leather off-cuts was prepared by cutting the off-cuts and then pulverize into powder using grinding. The treatment which was used to characterized the leather off-cuts in NaOH, EDTA, and H2SO4 at different molarity, subsequent characterization using FTIR was done. The result obtained varies at different molarity treatment. The NaOH treatment shows a progressive reduction to amine absorption of dechroming frequencies of 3254.61 CM-1, 3247.20 CM-1, 2917.61 CM-1, 2918.30 CM-1, 2917.63 CM-1 correspond to 0.2M, 0.4M, 0.6M, 0,8M, and 1.0M respectively. For H2SO4 , a similar trend was observed with a little fluctuation in the absorption band. For EDTA, the absorption from 3525.91 CM-1 , 3366.53 CM-1, 3522.24 CM-1 and 3517.45 CM-1 respectively was observed.
